MOSQUITO-BAR FRAME.

SPECIFICATION forming part of Letters Patent No. 439,256, dated October28, 1890.

Application filed April 2, 1890. Serial No. 346,332. (No model.)

To all whom it may concern.-

Be it known that we, FRANK CHEIsTOPHEE SOHWEND and JOSEPH BENTON WILsON,citi- Zens of the United States, residing at Montgomery, in the countyof Montgomery and State of Alabama, have invented certain new and usefulImprovements in Mosquito-Bar Frames; and we do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

Our invention relates to supports or frames for canopies or screens forprotecting persons from flying insects.

It consists in certain details of construction, as hereinafter setforth, and particularly pointed out in the claims.

Figure 1 represents an improved frame applied to a bedstead forsupporting a mosquito-bar, one of the cross-pieces being broken away.Fig.2 is a View, on an enlarged scale, showing how the parts fittogether.

The frame comprises two uprights A, which are adapted to be secured tothe head-board or post or foot-board or post of the bed B, preferably bymeans of screws 0. Te prefer to place them adjacent to the posts 6, inorder to give thegreatest spread to the mosquito-bar.

To the top of each upright is hinged an arm D, having its'rear endarranged to project somewhat beyond the back of the upright, as shown.In the front of the upright is cut a transverse notch a, and across thebottom of the arm D is a similar notch d. A brace E, consisting of a barhaving its ends shaped to enter the notches aand d by sliding into themlaterally supports the arm D when it has been raised to a horizontalposition.

Fastened to one edge of. each arm and at each end thereof is a tongue F,composed of a strip of wrought-iron. The tongue projects beyond the endof the arm and its Outer end f is turned at right angles, forming ahookshaped rest for the cross-pieces G, which are made long enough tofit the widest bed. They are adapted to engage with the tongues F bymeans of transverse saw-cuts g, extending partly through them frombelow. The sawcut slips down Over the tongue, bringing the cross-piecebetween the end of the arm and the hook f, the space being made ofsubstantially the same width as the cross-pieces, so that they arefirmly held and cannot swing about. By making the space between thesaw-cuts at the two ends of each cross-piece the same as the widthbetween the tongues on the rear ends of the arms after the uprights havebeen attached to the bed the frame formed by the arms and cross-piecesis sure to be rectangular. The frame can be applied to beds of differentwidths simply by making additional saw-cuts in the cross-pieces atsuitable distances apart. When the crosspieces are detached and thebraces slipped out, the arms can be folded down against the uprights,and the frame can then be packed for transportation or storage in a verysmall compass.

The frame is easily made, requiring no mortising. It is exceedinglycheap, and can be fitted by the purchaser to any width of bed.

Having thus described our invention, what we claim and desire to secureby Letters Patcut, isl 1. The combination, with the uprights, of thearms extending therefrom, having each a tongue composed of a strip ofmetal and a cross-piece having transverse saw-cuts to fit over thetongues, substantially as described.

2. The combination, with the uprights, of the arms extending therefrom,having at each end a tongue F, provided with a right-angled hook f, andcross-pieces Q, having saw-cuts g, adapted to fit over the tongues andto lie between the ends of the arms and the hooks f, substantially asdescribed.

3. An improved mosquito-bar frame consisting of the uprights A, havingthe notches a, the arms D, hinged to the uprights and having the notchescl, the braces E entering said notches, the tongues F, projecting fromthe ends of the arms and having hooks f, and the cross-pieces G, adaptedto receive sawcuts g at any point, whereby the frame is capable ofapplication to beds of different widths, substantially as described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
